DEFLECTOR AND VENTILATOR.

To all whom 'it may concern Be it known that I, SHEPHERD B. SHIP- LEY, a citizen of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented certain new and useful Improvements in Deflectors and Ventilators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to that class of dust and cinder guards for railway cars and other windows which are designed to be removably set in position at the edge of the window and project laterally therefrom and which also performs the function of a ventilator.

'Ihe object of the invention is to provide a simple and eh'icient dust and cinder guard so constructed as to o-perate as a ventilator by causing an outward suctionl of air from within the vehicle through the window to which it is applied.

Another object of the invention is to provide a device of this character which may be readily reversed and used at either side of the window.

With these and other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings: Figure l represents a perspective view of a portion of a railway car showing this improved guard applied; Fig. 2 is a similar view of the guard detached; Fig. 3 is a longitudinal vertical section taken on the line 3 3 of Fig. 2; Fig. 4 is a transverse section taken on the line 4-4 of Fig. 2; Fig' is a detail perspective view showing portions of the guard and window frame arranged in juxtaposition ready for connection; Fig. 6 is a plan View of the blank from which the form of guard shown in Figs. l to 4 is constructed; Fig. 7 is a perspective view of another form of the invention; Fig. 8 is a transverse section thereof; Fig. 9 is a transverse section of a guard shown composed of wood; Fig. l0 is a diagrammatic view showing the effect of the guard on the air currents whereby it performs its function as a ventilator; Fig. l1 is a View similar to Fig.

" 4 showing a slightly modified form of the invention.

In the embodiment illustrated a portion of a railway car A is shown having a window B therein which may be of any suitable construction having the usual frame and sashes. The combined guard and ventilator 1 shown in Figs. 1 to (i is constructed of any suitable material, sheet metal being preferably employed for the main portion or plate 2, which is mounted on a rigid sash support 3 preferably constructed of wood but it may be of any suitable material. rIhis support 3 is preferably beveled in the same direction at its opposite ends to snugly lit within a car window, the sill and the lower edge of the sash of which are usually beveled or inclined, and said support is designed to hold the sash in raised position. This sash support 3 is provided on its opposite side edges with headed studs 4 which are adapted to enter key hole slots 5 formed in plates secured to the window frame (see Fig. 5).

The three walled deflecting plate 2 shown in Figs. 1 to 4 is preferably constructed from a single sheet of bendable material the blank for which is shown in Fig. 6 but it may, if desired, be formed from separate pieces as shown in somev of the other figures and as will be hereinafter described.

The blank shown in Fig. G comprises two plates 6 and 7 connected by a strip 9 at one end, the portion 9 of the strip which is connected with the plate 7 being wider than that connected with the plate 6 and said strip is adapted to be folded on the dotted line 10 during the formation of the guard as will be hereinafter described. The plate 6 is folded longitudinally on the dotted lines 11, 12, 13 and 14 to form the attaching flanges 15 and 16 which extend laterally at the rear edge of the plate and are adapted to be secured by fastening elements to the supporting strip 3, the metal forming these flanges being of double thickness as is shown clearly in Fig. 4. This folding of the plate 6 provides laterally spaced outer walls or plates 17 and 13 between which the plate 7 is designed to extend when the strip 3 has been properly folded to produce the flange 19 at the top of the guard, said flange being preferably curved transversely as shown clearly in Fig. 3. Before its insertion be of the plates 17 and 18 as is shown clearly inH Fig. 4. These flanges 23 and 24 also extend laterally i on either side of the deflecting plate beyond the outer faces of said plates 17 and 18 for a purpose to be described.

d The plate 6 is provided between the flanges 15 and 16 with a longitudinally extending groove 25 which is adapted to receive the free edge of the plate 7 when the parts are assembled and as is clearly shown in Fig. 4. The plates 17 7 and 18 are secured together by fastening bolts on which are mounted between the respective plates spacing sleeves 26 any desired number of which may rbe employed according to the number of bolts used and which are designed to space the plates the desired distance apart. The plate 7 projects at its upper end and its outer side edge beyond the plates 17 and 18 a Asutlicient distance to permit the cinders and dust which come in contact with the guard to pass into the space between the outer plate which is arranged toward the front of the car and the plate 7 and through which space they are guided to the lower end of the guard and discharged therefrom in a plane below the car window.

The laterally projecting flanges 23 and`24 at the outer edge of the guard and the flange 19 at the top thereof form important features of this invention and are designed to so direct the currents of air which impinge against the outer face of the defiector as to cause them to circle in the direction shown in Fig. 10 at t-he rear of said guard thereby forming a circular draft at the rear of the guard opposite the open window which sucks out the air from within the car and serves to thoroughly ventilate the car drawing out the impure air from within. The flange 19 is curved transversely to facilitate the deflection of the cinders away from the oar window and prevent their entrance over the top of the deector or guard. In the use of this improved guard the window sash having been raised a suitable distance to permit the support. 3 to beinserted thereunder one ofthe studs 4 on said support is engaged with the key hole slot 5 in the plate on the window frame whereby said guard is held securely in position with the deflecting or body portion thereof eX- tending laterally at right Yangles to the side wall of the car as is shown clearly in Fig. 1. Ihen the device is in this position and the train is moving forward in the direction of the arrow c the currents of air produced by the onrushing of the train will come in contact with the outer face of the guard 1 and Ythe cinders carried by said current-s will be deflected downwardly, some entering the pockets formed between the plates 17 and 7 inthe manner above described and the air coming-in contact with'the side flange 24 at the front or outer edge of the deiector 'willbecaused to pass rearwardly around said flange and will take the course indicated by the arrows b thereby, having a tendency toY produce a vacuum decreasing the air pressure at Vthe window immediately behind the deflector. This causes the Aair in the car to be sucked or pulled out ofthe windows. This isV especially desirable for use on the windows of smoking cars to draw out the smoke from the inside ofthe car.

In the form shown in Figs. 7 and 8 a single walled guard' 1ZL is shown somewhat similar to the guard shown in Figsal t0 4, being provided with laterally extending fianges 28@- and 24u at its free side edge and a flange 19@L at its upper edge7 said {ianges projecting on opposite sides of the plate and `being designed to accomplish the function of the same flanges of the other ngures, that is, to deflect the cinders and dust downwardly and prevent their entrance into the car window and to cause the currents of air i'vhich impinge thereagainst to sweep around the guard and create a suction like draft to draw the impure air from the car. The supporting strip `3a' thereof is designed'to fit withinV the window frame in the same manner as the strip 3 of the'other figures vand is provided with the same fastening means for securing it within the window.Y

In Fig. 9 the guard isshown constructed of wood or other similar material and the plate 1b thereof has a 'dovetailed connection at its sideedges Ywiththe supporting strip 3b and the flange member 23b but it may be secured thereto in any other suitable or desired manner.

The operation'of the forms shown in Figs. 7 8 and 9 is the same as that Vof the other figures and therefore need not be again described. p

In Fig. 11 of the drawings'I have shown the plates V17 and 18V disposed at -aslight angle with respect tothe central plate 7 so as to increase the space for the cinders and thus increase plates. f' `1 lVhile I yhave described my invention with `more or less minuteness as regards details and as being embodied in certain precise forms,V I do not desire to be limited thereto unduly any more than is pointed out 4in the claims. On the contrary, I contemplate all proper changes in form7 construction and arrangement, the omission of immaterial elements and substitution'of equivalents as i Ycircum'sta-nces may suggest or render expedient.

I c'la-iin'asmy invention: f 1. A deilecto'r and ventilator for vehicle ioo the draft between the spaced Windows comprising a guard composed of laterally spaced plates one of Which projects beyond the other at one end and one side and provided With flanges extending laterally on opposite faces of said projecting end and side.

2. A deflector and ventilator for vehicle Windows comprising a guard plate struck from a single sheet of bendable material and foldable to form laterally spaced plates one of Which is provided at its upper end and outer edge With laterally extending ianges.

3.
